Control Valve Type
- Sep 12, 2018 -

There are many types of valve bodies for regulating valves. Commonly used are straight-through single-seat, straight-through two-seat, angular, diaphragm, small flow, three-way, eccentric rotation, butterfly, sleeve, spherical and so on. In the specific choice, you can make the following considerations:


Mainly based on factors such as selected flow characteristics and imbalance forces.

When the fluid medium is a suspension containing a high concentration of abrasive particles, the internal material of the valve is tough.


Due to the corrosive nature of the media, try to choose a simple valve.

When the temperature and pressure of the medium are high and the change is large, the valve and the material of the valve seat should be selected to be small in temperature and pressure.


Flashing and cavitation are only produced in liquid media. In the actual production process, flashing and cavitation will form vibration and noise, shortening the service life of the valve, so the valve should be prevented from flashing and cavitation when selecting the valve.
